Nvidia 在台北 Computex 再次把 Windows-on-Arm 电脑推到台前，情景与约 15 年前在台北 101 附近的 W Hotel 发布会颇为相似。彼时 Qualcomm、Texas Instruments 和 Nvidia 展示新一代省电移动电脑的参考设计，但由于 Windows 8 触控体验不佳、软件兼容问题频发，这一尝试很快失败；Nvidia 当年的 SoC 甚至被命名为 Kal-El Superchip。如今，Jensen Huang 以新的 RTX Spark Superchip 重新包装这一方向，试图让消费者重新相信 Arm Windows 笔电的前景。
与 2011 年相比，Nvidia 与 Huang 的地位已完全不同：从面向玩家显卡市场的公司，变成市值 5 兆美元、驱动人工智能革命的核心企业。Huang 在 Computex 说，100% 的 PC 制造商都已加入 RTX Spark 计划，并将远程参加 Microsoft Build 与 Satya Nadella 对谈；前 Windows 负责人 Steven Sinofsky 也回忆起当年首代 Surface 采用 Nvidia Tegra ARM 芯片的往事。文章同时指出，长期 Windows 用户期待更好的机器，而作者本人使用的 Qualcomm 版 Lenovo 笔电电池续航表现出色。
尽管如此，文章对 RTX Spark 的关键疑问仍集中在续航与能效：若只是达到 Intel 级性能，却只有 Intel 级电池寿命，就难以真正改变市场。分析师 Bryan Ma 认为，这类产品短期内难以明显拉动出货，因为定位会非常高端、价格也偏贵，更像是面向发烧友和创意专业人士的“halo device”；但它可能改变 PC 的使用方式，并把原本疲弱的 AI PC 叙事推向更激进的方向。Huang 与 Qualcomm CEO Cristiano Amon 都强调，面向 AI agents 的机器需要专门设计，而 Arm 路线已被证明更有利于提升 Windows 的省电效率。
Nvidia is bringing Windows-on-Arm PCs back to the stage at Computex in Taipei, echoing the launch event held roughly 15 years ago at the W Hotel near Taipei 101. Back then, Qualcomm, Texas Instruments and Nvidia showed reference designs for a new class of power-efficient mobile computers, but the effort quickly failed because Windows 8 was not touch-friendly enough and software incompatibilities were widespread; Nvidia even named its chip the Kal-El Superchip. Now Jensen Huang is repackaging the idea with the RTX Spark Superchip, trying again to persuade consumers that Arm-based Windows laptops have a future.
Compared with 2011, both Nvidia and Huang are in a radically different position: the company has moved from gaming graphics to a $5 trillion role at the center of the AI revolution. Huang said at Computex that 100% of PC makers are signed up for RTX Spark, and he is set to appear remotely at Microsoft Build with Satya Nadella; former Windows chief Steven Sinofsky also recalled that the first Surface used Nvidia Tegra ARM chips. The piece notes that long-time Windows users want better machines, while the author’s Qualcomm-powered Lenovo laptop has outstanding battery life.
Even so, the main questions about RTX Spark remain endurance and power efficiency: if it delivers Intel-like performance but only Intel-like battery life, it does not really change much. IDC analyst Bryan Ma argues that such machines are unlikely to move shipments much in the near term because they will be premium, expensive devices aimed at enthusiasts and creative professionals, though they could still change how PCs are used and push the weak AI PC narrative in a more aggressive direction. Huang and Qualcomm CEO Cristiano Amon both say future AI agents need purpose-built hardware, and the article concludes that Arm is already the clearest path to better power efficiency on Windows.
